The Powercore 2 is the measure which others aim for. With its lightweight extruded aluminum oval canister mated to a perforated core, this silencer is above the competition. The Powercore 2 silencer provides a strong performance edge for any 2-stroke machine and the performance flow end cap and front stinger are stainless steel for unbeatable durability and an unmatched look.

The sleeve of the Powercore 2 silencer is constructed from extruded aluminum to provide a lightweight design.

FMF incorporated a tuned perforated core for exceptional performance.

FMF made sure the Powercore 2 silencer was also durable by using stainless steel on the performance flow end cap and the stinger.

FMF makes it easy to perform maintenance on the Powercore 2 silencer by using removable bolts to break it down.

I've ran this coupled with a fatty on every 2 stroke I've owned since 1994. They work and are rugged too. I've bent them, bent them back and ran them. Great performance over the entire powerband. Would recommend this too any MX or enduro rider.

Product came as shown and shipping was out faster than I expected. Had a moment of panic until I realized the silencer support tab was missing and we had to weld a new on to the frame. Very pleased with the purchase and service.

This exhaust silencer is about the best you can get.She sounds mean! It makes it even better when you hook it up with a fatty pipe.Definetly felt the difference in power and powerband.Very durable.The fatty and powercore 2 have been on my 280cc 2002 Yamaha blaster for 2 years! Well worth it!

This silencer really works good i was going to get a shorty but I decided to go with the powercore2 because I do more woods riding. I love it because it made my power band on my KTM more snappy with out being to much for the woods.

The stock exhaust on my sons PW50 was damaged and I replaced it with this aftermarket silencer. No power gains since I only have the silencer. I do plan on getting the fatty pipe but this silencer fits well with the stock header.

Great aftermarket silencer. Sounds beautiful! I installed with with a new Fatty pipe and got a great power increase across the power band. The rear-most attaching bracket rubs a little on the rear fender, but other than that, absolutely perfect fit.

I Installed the Power core 2 on my Rm 125 because I already had a fmf pipe and I needed to match. I got the regular one because I felt like the shorty's were too loud and I was concerned about loosing top. Not expecting much of a difference I was actually pleasantly surprised when I noticed a small gain in the Mid / Bottom and no noticeable loss of top / overrev. The power core 2 is about an inch shorter overall then the stock muffler, just FYI, and has a sweet exhaust note. Not to Raspy and loud. BRRAAAAPP.

The FMF Shorty pipe is a good race pipe. If you're looking for a cheap pipe and dont mind it being loud this would be a good pipe for you. Also i would suggest getting it tuned as far as jetting goes with the pipe. You can go without it and be fine but you won't be running nearly any back pressure. Thats the reason why i didnt give it 5 stars. If you jet your bike right you shouldn't have a problem with the "lag" i got up top in the rev range. Again, this is a loud pipe. It isn't insane if you keep fresh packing foam in it but if your not up for replacing it, it will sound like you have a can as a slip on. Loud, Raspy, and obnoxious. With the packing foam it sounds great though!! Wouldnt recommend it for woods riding. Good for MX.

Silencer is the second best invest on my bike besides the Fatty pipe, nothing has more Bolt on power. Bored the bike to a 300cc, then added the silencer and it felt like it got bored out even more. Instant power and a quicker throttle response. I also have a turbine core i use when we ride where they are required but would reccommend the Powercore 2 over it. The power core gives a little more power, and sound great. not as loud as the shorty, but not as quiet as the turbine core, its an overall great investment to your bike.
